The storage medium 33 is used to store information of the developing cartridge. The storage medium 33 has an electrical contact surface 331, which can be a surface on the storage medium 33 or a surface on a contact sheet electrically connected to the storage medium. When the developing cartridge is installed in the image forming device, the electrical contact surface 331 can contact a component in the image forming device to transmit information to the image forming device, so that the developing cartridge is recognized by the image forming device.

[0061] As shown in Figure 3 The first bracket 31 is connected to the cartridge body 10, and the second bracket 32 is detachably connected to the first bracket 31. The second bracket 32 has a first mounting part 323, and the storage medium 33 is mounted on the first mounting part 323. The storage medium 33 is provided with mounting ribs 332 on both sides in the second direction Y, and the first mounting part 323 is provided with mounting rails 323a on both sides in the second direction Y, which extend along the first direction X.

[0062] During the process of mounting the storage medium 33 to the first mounting portion 323 along the first direction X, the mounting rib 332 is guided by the mounting rail 323a, and when the storage medium 33 is completely mounted to the first mounting portion 323, the mounting rib 332 is limited by the mounting rail 323a to prevent the storage medium 33 from being separated from the first mounting portion 323. In the embodiment, the storage medium 33 is stably supported by the second support 32 only through the clamping limiting structure, and in some embodiments, the storage medium 33 and the second support 32 can also be connected by adhesives such as glue.

[0063] Regarding the specific structure of the first support 31 and the second support 32, the present application provides the following various embodiments.

[0064] Embodiment one

[0065] In the embodiment, as shown in Figure 3 and Figure 4 , the first support 31 has a first joint portion 311 and a second joint portion 312, and the second support 32 has a third joint portion 321 and a fourth joint portion 322. The first joint portion 311 cooperates with the third joint portion 321, and the second joint portion 312 cooperates with the fourth joint portion 322, thereby realizing the detachable connection of the first support 31 and the second support 32. When it is necessary to detach the second support 32 from the first support 31, as long as the cooperation of the first joint portion 311 and the third joint portion 321 and the cooperation of the second joint portion 312 and the fourth joint portion 322 are released, the first support 31 does not need to be detached from the box body 10 in advance, thereby simplifying the detachment process of the second support 32.

[0066] Specifically, the first support 31 has a containing portion 313, and at least part of the third joint portion 321 and the fourth joint portion 322 are contained in the containing portion 313 when the first support 31 is connected with the second support 32. The containing portion 313 can play a protective role on the third joint portion 321 and the fourth joint portion 322, preventing external impact from acting on the third joint portion 321 and the fourth joint portion 322, and improving the stability of the connection of the second support 32 and the first support 31.

[0067] The containing portion 313 has a hollow structure and has an opening in the third direction Z. The containing portion 313 is provided with a support table 317 on the end portion in the third direction Z. The support table 317 supports the first support 31 in the third direction Z, so that the first support 31 is kept at a fixed position in the third direction Z, specifically, the support table 317 supports the first mounting portion 323. The support table 317 is arranged adjacent to the containing portion 313, and is preferably located around the containing portion 313. The first joint portion 311 and the second joint portion 312 are respectively located at both ends of the containing portion 313 in the first direction X. Correspondingly, the third joint portion 321 and the fourth joint portion 322 are distributed along the first direction X, and the third joint portion 321 is farther away from the first end 11 than the fourth joint portion 322 in the first direction X.

[0068] Preferably, the first joint 311 and the second joint 312 are in a slot structure, the third joint 321 and the fourth joint 322 are in a hook structure, the third joint 321 can be clamped with the first joint 311, and the fourth joint 322 can be clamped with the second joint 312, so that the first support 31 and the second support 32 are fixedly connected in a clamped and matched manner without the need for fastening by screws or the like.

[0069] More specifically, the fourth joint 322 is in a hook structure, including a hook portion 322a, an elastic portion 322b, and a dismounting portion 322c, the hook portion 322a can be clamped with the side wall of the second joint 312, the elastic portion 322b can be deformed, one end of the elastic portion 322b is connected with the first mounting portion 323, and the other end is connected with the hook portion 322a, and the dismounting portion 322c is connected to one side of the hook portion 322a away from the elastic portion 322b; wherein, when the first support 31 is connected with the second support 32, the hook portion 322a and the elastic portion 322b are located in the accommodating portion 313, and the dismounting portion 322c is located outside the accommodating portion 313.

[0070] Optionally, the fourth joint 322 is in a U-shaped elastic cantilever structure as a whole. In the third direction Z, the dismounting portion 322c is located above the hook portion 322a. An inclined surface is arranged on the hook portion 322a, and the inclined direction of the inclined surface intersects the first direction X and the third direction Z, and specifically can be: extending leftward in the first direction X while extending upward in the third direction Z.

[0071] The following is a preferred way to install the second support 32 provided by the present embodiment to the first support 31: as shown in Figure 5 and Figure 6 shown, the second support 32 is moved towards the first support 31 from above the first support 31 in the third direction Z, the third joint 321 is jointed with the first joint 311 by tilting the second support 32, then the fourth joint 322 is pressed down, so that the inclined surface on the hook portion 322a contacts the frame on the second joint 312, the second joint 312 makes the elastic portion 322b elastically deform to drive the fourth joint 322 to elastically avoid the frame on the second joint 312, after the inclined surface on the hook portion 322a passes the frame on the second joint 312, the elastic portion 322b elastically recovers and makes the fourth joint 322 jointed with the second joint 312, and the second support 32 is fixedly installed on the first support 31. At this time, the elastic portion 322b is located inside the accommodating portion 313, and the dismounting portion 322c is located outside the accommodating portion 313. The elastic portion 322b and the support table 317 limit the movement of the second support 32 in the third direction Z, that is, the elastic portion 322b limits the movement of the second support 32 in the installation direction.

[0072] Specifically, in the third direction Z, the first joint 311 and the second joint 312 limit the second support 32 to prevent it from moving up and down; in the first direction X, the first joint 311, the hook 322a, and the elastic part 322b work together to prevent the second support 32 from moving in the first direction X; in the second direction Y, the width of the third joint 321 matches the width of the receiving part 313, so that the third joint 321 matches the receiving part 313 to prevent the second support 32 from moving in the second direction Y. In this embodiment, the first support 31, the second support 32, and the storage medium 33 do not move relative to the housing 10. In some embodiments, the first support 31, the second support 32, and the storage medium 33 may also move relative to the housing 10.

[0073] When it is necessary to detach the second bracket 32 ​​from the first bracket 31, a force in the first direction X to the right can be applied to the detachment part 322c, causing the elastic part 322b to deform elastically. At this time, the fourth joint part 322 can be disengaged from the second joint part 312. Then, the second bracket 32 ​​is tilted upward and lifted, and the first joint part 311 and the third joint part 321 are disengaged, thus removing the second bracket 32 ​​from the first bracket 31. Finally, the storage medium 33 is removed from the second bracket 32, and the information in the storage medium 33 can be corrected or added using a reader / writer.

[0074] It is known that the third joint 321 can also have a certain elastic deformation capability so as to avoid the first joint 311 when installing and disassembling the second bracket 32; the end of the third joint 321 can also be chamfered to further facilitate disassembly and installation.

[0075] In this embodiment, instead of using screws or other cumbersome methods to fix the second bracket 32 ​​to the first bracket 31, the second bracket 32 ​​is conveniently installed on the first bracket 31 using a snap-fit ​​connection structure, and can be easily disassembled, simplifying the assembly and disassembly of the developing cartridge.

[0076] In addition, such as Figures 3-6 As shown, the first support 31 further includes an abutment portion 314 and a fastening portion 315. The abutment portion 314 is a protruding plate extending in the third direction Z, used to contact the image forming apparatus. The fastening portion 315 can be connected to the cover 101, so that the first support 31 is connected to the cover 101, thereby allowing the first support 31 to be supported by the housing 10. It is understood that, to ensure a stable connection between the first support 31 and the cover 101, the first support 31 can be further fixed by fasteners such as screws.

[0077] In this embodiment, the joint structure on the first bracket 31 can be exchanged with the joint structure on the second bracket 32.

[0078] In some embodiments, the first support 31 and the cover 101 can be integrally formed to reduce the components of the developing cartridge, control the difficulty of production and assembly of the developing cartridge, or the first support 31 is directly connected with the cartridge body 10.

[0079] Embodiment Two

[0080] This embodiment changes the embodiment one, and the difference between this embodiment and the embodiment one is that the first support 31 is not provided with the accommodating part 313, but is provided with the guiding part 316, and the second support 32 is provided with the guided part.

[0081] As shown in Figures 7-10 the first support 31 has the first engaging part 311, the second engaging part 312 and the guiding part 316, and the second support 32 has the third engaging part 321, the fourth engaging part 322 and the guided part 324, the first engaging part 311 cooperates with the third engaging part 321, the second engaging part 312 cooperates with the fourth engaging part 322, and the guiding part 316 cooperates with the guided part 324. In an embodiment, the first support 31 can be provided with the guided part, and the second support 32 can be provided with the guiding part.

[0082] Specifically, the guiding part 316 extends along the first direction X and has two guiding inclined surfaces distributed along the second direction Y, and correspondingly, the guided part 324 also extends along the first direction X and has two guided inclined surfaces distributed along the second direction Y, the guiding inclined surface can guide the guided inclined surface. When the second support 32 is mounted on the first support 31 along the first direction X, the guided part 324 is guided by the guiding part 316 to slide along the first direction X. The guided part 324 engages with the guiding part 316 in the at least partially covering manner in the third direction Z.

[0083] Preferably, the guiding part 316 is a wedge-shaped protrusion protruding in the third direction Z, the guided part 324 is a wedge-shaped groove recessed in the third direction Z, and the wedge-shaped groove has an opening downward in the third direction Z, that is, along the third direction Z, the size of the guiding part 316 and the guided part 324 in the second direction Y gradually increases or decreases.

[0084] The width of the guiding part 316 and the guided part 324 in the second direction Y is matched to be set so that when the guided part 324 is mounted on the guiding part 316, the two parts are tightly fitted to prevent the second support 32 from moving in the second direction Y relative to the first support 31. With the guiding part 316 extending upward, the distance between the two guiding inclined surfaces gradually increases; with the guided part 324 recessing upward, the distance between the two guided inclined surfaces gradually increases. Therefore, the guiding inclined surface limits the guided inclined surface in the third direction Z to prevent the second support 32 from moving in the third direction Z relative to the first support 31.

[0085] More specifically, the first engaging part 311 is located at the end of the guiding part 316 away from the box body 10 in the first direction X, the first engaging part 311 is a hook structure, and the hook structure is located between two guiding slopes in the second direction Y; the third engaging part 321 is located at the end of the guided part 324 away from the box body 10 in the first direction X, the third engaging part 321 is a frame or a hole, and the third engaging part 321 is located between two guided slopes in the second direction Y. The hook structure can be clamped in the third engaging part 321 to prevent the second support 32 from moving in the first direction X.

[0086] In the first direction X, the second engaging part 312 is closer to the first end 11 than the first engaging part 311, and the second engaging part 312 is the end surface of the guiding part 316 away from the box body 10 in the first direction X; in the first direction X, the third engaging part 321 is closer to the first end 11 than the fourth engaging part 322, and the fourth engaging part 322 is located at the end of the guided part 324 away from the box body 10 in the first direction X, and the second engaging part 312 can abut against the fourth engaging part 322 to further prevent the second support 32 from moving in the first direction X.

[0087] Preferably, the second engaging part 312 has two, respectively located on both sides of the first engaging part 311 in the second direction Y; the fourth engaging part 322 has two, respectively located on both sides of the third engaging part 321 in the second direction Y.

[0088] Preferably, the hook structure is provided with a slope 311a, and the extension direction of the slope 311a intersects the first direction X and the third direction Z, that is, the slope 311a extends leftward in the first direction X while extending upward in the third direction Z. The hook structure has a certain elastic avoidance capability, that is, the hook structure is an elastic part, when the second support 32 is installed on the first support 31 in the first direction X, the third engaging part 321 presses the slope 311a on the first engaging part 311, the first engaging part 311 elastically avoids the third engaging part 321, and after the third engaging part 321 passes the first engaging part 311, the first engaging part 311 elastically recovers and engages with the third engaging part 321. In the first direction X, the first engaging part 311 is located to the right of the third engaging part 321, and the first engaging part 311 can prevent the second support 32 from moving to the right in the first direction X. The second engaging part 312 abuts against the fourth engaging part 322, and the third engaging part 321 is located to the left of the fourth engaging part 322 in the first direction X, and the third engaging part 321 can prevent the second support 32 from moving to the left in the first direction X, thereby fixing the second support 32 on the first support 31.

[0089] When the second support 32 needs to be removed from the first support 31, the inclined surface 311a is pressed to elastically deform the first engaging portion 311 to release the restriction on the second support 32, i.e. the inclined surface 311a can be regarded as a removal portion, and then the second support 32 is moved to the right along the first direction X.

[0090] In some embodiments, the second support 32 is engaged with or removed from the first support 31 along the second direction Y or the third direction Z, and the corresponding structure is changed according to the mounting and removal direction of the second support 32. For example, if the mounting direction of the second support 32 is the second direction Y, the guided portion 324 and the guiding portion 316 extend along the second direction Y, i.e. the extension direction of the guided portion 324 and the guiding portion 316 is the same as the mounting direction of the second support 32.

[0091] Embodiment Three

[0092] This embodiment is a modification of the first embodiment, and the difference between this embodiment and the first embodiment is that the structure of the identification assembly is different, and in this embodiment, the storage medium 33 does not need to be removed to modify the information of the storage medium 33.

[0093] As shown in Figure 11 and Figure 12 , the identification assembly includes a first support 51 and a second support 52.

[0094] The first support 51 and the cover 101 form a space with an opening. The cover 101 is provided with a first support hole 101a opening toward the first direction X; the first support 51 includes a support portion 511 surrounding the space, and the support portion 511 is provided with a second support hole 512 opening toward the first direction X, and the second support hole 512 is farther away from the first end 11 than the first support hole 101a. The first support 51 can be detachably connected with the cover 101 by a buckle connection or a screw fixation, or the first support 51 and the cover 101 can be integrally formed or directly connected with the box body 10.

[0095] The second support 52 is located in the space formed by the first support 51 and the cover 101, and the second support 52 includes a second mounting portion 521, a first support column 522 and a second support column 523. The second mounting portion 521 is used for mounting the storage medium 33, the first support column 522 and the second support column 523 extend in the first direction X and are located in the first support hole 101a and the second support hole 512, respectively.

[0096] In the radial direction intersecting the first direction X, the sizes of the first support column 522 and the second support column 523 are respectively smaller than the sizes of the first support hole 101a and the second support hole 512, so that the second bracket 52 can be moved relative to the cover 101 and the first bracket 51 while being supported by the cover 101 and the first bracket 51, i.e. the second bracket 52 and the storage medium 33 can be moved relative to the cartridge 10.

[0097] Since the storage medium 33 needs to store the information of the developing cartridge so as to be recognized by the image forming apparatus, the tester 91 (a reader / writer) is needed to input information to the storage medium 33 or change the information of the storage medium 33. The tester 91 comprises an electric contact pin 911 which can be in contact with the electric contact surface 331 so as to make the tester 91 input information to the storage medium 33.

[0098] In the embodiment, as shown in Figures 13-15 the recognition assembly further comprises an auxiliary tool for making the tester 91 conveniently input information to the storage medium 33. The auxiliary tool is preferably an auxiliary member 53 which is directly or indirectly positioned on the cartridge 10, and the auxiliary member 53 positions the storage medium 33 and ensures that the electric contact pin 911 is in electric contact with the electric contact surface 331.

[0099] Specifically, the auxiliary member 53 comprises a first hole 531, a sleeving part 532, a first limiting part 533, a second limiting part 534 and a third limiting part 535.

[0100] The first hole 531 is a through hole extending in the third direction Z, the width of the first hole 531 matches the width of the end of the electric contact pin 911, and the first hole 531 is used to guide the end of the electric contact pin 911 to move downward and be positioned.

[0101] In the first direction X, the first hole 531 is above the sleeving part 532, the sleeving part 532 comprises a second hole 536 which is in communication with the first hole 531 and corresponds to the electric contact surface 331 of the storage medium 33 to expose the electric contact surface 331, and the second hole 536 is used to make the electric contact pin 911 pass through to contact the electric contact surface 331.

[0102] The first limiting part 533, the second limiting part 534 and the third limiting part 535 are located around the auxiliary member 53, and the number of limiting parts is not limited in the embodiment, and only the three limiting parts are exemplified. The first limiting part 533 and the second limiting part 534 are located on the two sides of the auxiliary member 53 in the second direction Y, and the third limiting part 525 is located on the side of the auxiliary member 53 away from the first end 11 in the first direction X. The first limiting part 533 extends downward relative to the rest of the auxiliary member 53 in the third direction Z, and the second limiting part 534 and the third limiting part 535 are more protruding in the radial direction relative to the rest of the auxiliary member 53.

[0103] When information needs to be input to the storage medium 33, the auxiliary member 53 is first placed above the second support 52, and then the auxiliary member 53 is moved downward along the third direction Z, the sleeve part 532 is sleeved on the second mounting part 521 of the second support 52 and is supported by the first support 51, the sleeve part 532 presses the second support 52 downward, so that the first support column 522 and the second support column 523 of the second support 52 respectively contact and are supported by the lowermost faces of the first support hole 101a and the second support hole 512, and further so that the second support 52 cannot move in the third direction Z.

[0104] In the second direction Y, the first limiting part 533 is located in the gap between the rear side of the second support 52 and the rear side of the support part 511, and the second limiting part 534 is located in the gap between the front side of the second support 52 and the front side of the support part 511, so that the second support 52 cannot move in the second direction Y. The second limiting part 534 abuts against the support part 511, so that the auxiliary member 53 is further supported by the first support 51.

[0105] In the first direction X, a fourth limiting part (not shown) is further provided on the side of the auxiliary member 53 close to the first end 11, and the fourth limiting part is located between the left side of the second support 52 and the side wall of the cover 101, so that the second support 52 cannot move in the first direction X. That is, in the embodiment, the auxiliary member 53 fixes the second support 52 and the storage medium 33, so as to prevent the storage medium 33 from shaking when the tester 91 inputs information to the storage medium 33, and further to prevent unstable transmission of information.

[0106] When the auxiliary member 51 is positioned on the second support 52, the electrical contact face 331 is exposed outside through the second hole 536, and at this time, the tester 91 is moved downward along the third direction Z, the electrical contact pin 911 is in electrical contact with the electrical contact face 331, and the end part where the electrical contact pin 911 is located is positioned by the first hole 531, so as to further ensure stable contact between the electrical contact pin 911 and the electrical contact face 331, and ensure stable transmission of information. It can be understood that the electrical contact pin 911 and the electrical contact face 331 can be in direct contact or indirect contact, as long as information transmission can be completed.

[0107] In the embodiment, the auxiliary member 53 and the tester 91 can be used when the storage medium 33 is installed on the developing cartridge, and can also be used when the storage medium 33 is not installed on the developing cartridge.

[0108] Embodiment Four

[0109] The embodiment changes the embodiment three, and the difference between the embodiment and the embodiment three is that the structure of the identification assembly is different.

[0110] As Figure 16 andFigure 17 As shown, the recognition assembly is provided with only one bracket 54, which includes a third mounting portion 541 for mounting the storage medium 33, and the bracket 54 is immovable relative to the box body 10 with the storage medium 33. The sleeve portion 532 of the auxiliary member 53 matches the length of the third mounting portion 541 in the second direction Y and the first direction X, and the auxiliary member 53 is sleeved downward on the third mounting portion 541 along the third direction Z, so that the auxiliary member 53 is supported by the bracket 54.

[0111] The auxiliary member 53 can also be provided with a limiting or supporting structure, so that the auxiliary member 53 is positioned on the box body 10 or the cover 101. The electrical contact pin 911 is accurately aligned with the electrical contact surface 331 through the first hole 531 and the second hole 536 to realize electrical contact, thereby realizing input of information. In this embodiment, the cooperation between the auxiliary member 53 and the bracket 54 is similar to the cooperation between the auxiliary member 53 and the second bracket 53 in Embodiment Three, and thus will not be described again.

[0112] It can be understood that for the movable bracket and the immovable bracket, the auxiliary member 53 can be changed according to different structures of the bracket, or can be universal for the two different brackets, and the auxiliary member 53 can be directly or indirectly positioned on the box body 10 and assist the tester in inputting information to the storage medium 33.

[0113] It can be understood that the bracket 54 can be detachably connected with the cover 101 through a buckle connection or a screw fixing connection, or the bracket 54 and the cover 101 can be integrally formed, and the bracket 54 and the storage medium 33 are immovable relative to the box body 10.

[0114] The bracket structure in this embodiment can also be the same as that in Embodiment One and Embodiment Two.
